Field of work: Mathematical analysis and nonlinear partial differential equations.

The successful applicant will be expected to perform research in the above-mentioned field, with a focus on reaction-cross-diffusion systems or two-phase flow. The research will either be centered around wellposedness and qualitative behavior, or the derivation of singular limits and effective equations.

We are looking for: 

  • A motivated, outstanding student with a master’s degree in mathematics and a strong background in analysis and partial differential equations. Prior knowledge in nonlinear parabolic and/or hyperbolic equations is desirable.
  • The MSc degree should be completed or close to completion.

What we offer:

  • WIAS Berlin is a premier research institution known for its strength in mathematical modeling and partial differential equations, dynamical systems, optimization, and applied mathematics in general.
  • Payment according to the collective agreement for the public service (TVöD Bund) includ-ing the usual social benefits (30 vacation days in a 5-day week, company pension plan); subsidy for the company ticket for public transport
  • Mobile working is possible.
